[PATCH 1/3] auxdisplay: panel: Change comments to silence fallthrough warnings

[Miguel Ojeda]

Compiling with W=1 with gcc 7.2.0 gives 3 warnings like:

  drivers/auxdisplay/panel.c: In function âpanel_process_inputsâ:
  drivers/auxdisplay/panel.c:1374:17: warning: this statement may fall
  through [-Wimplicit-fallthrough=]

I saw this while fixing the ones reported by the build service.
I will queue it up for 4.17.
